Implantable Collamer Lens or ICL
Implantable collamer lens or ICL, called by its manufacturer Visian ICL, is a soft, flexible gel-lens used in refractive surgeries for the permanent correction of myopia (nearsightedness), made of a collagen copolymer material, named by combining “collagen” and “polymer”. The ICL procedure is a popular alternative to LASIK and PRK since it requires no removal of the corneal tissue and reportedly produces better visual results.
The ICL procedure is a type of refractive surgery performed by an ophthalmologist in which the ICL is surgically implanted inside the eye, where it resides permanently. The ICL requires no maintenance after the procedure and functions very similarly to contact lenses in improving visual acuity. For most patients, ICL provides permanent freedom from eyeglasses or contact lenses.
